To all whom it may concern:

Be, it known that :we, JAMES and James A. GRAHAM, citizens of {theUnited States, residing; at Thompsonville, in the county of Franklin andState of Illinois, have invented certain new. and useful Improvements inSubsoilers,of which the followingis a specification,reference beinghadto the accompanying drawings.

This invention relates to certain improve ments in subsoilers and theobject of the invention is to provide 'a device of this generalcharacter having novel and improved means whereby the same may beoperatively connected with the beam of a plow proper with convenienceand facility. and in such a manner whereby the depth of penetration ofthe subsoiler may be readily regulated, as the necessities of. practicemay require.

The invention consists in the, details of construction and in thecombination and arrangement of the several parts of our improvedsubsoiler whereby certain important advantages are attained and thedevice is rendered simpler, less expensive and othelfi.

wise more convenient and advantageous for use, all as will behereinafter more fully set forth.

The novel features of the invention will be carefully defined in theappended claim.

In order that our invention may be the better understood, we will nowproceed to describe the same with reference to the accompanyingdrawings, wherein Figure 1 is a view in side elevation of a plow showinga subsoiler constructed in accordance with an embodiment'ot ourinvention in applied position thereon; Fig. 2 is a sectional view takensubstantially on the line 22 of Fig. 1'; and Fig. 3 is a sectional viewtaken substantially on the line e 3 of Fig.1.

As disclosed in the accompanying drawings, 1 denotes a plow beam asgenerally employed in connection with a walking 4 or sulky plow and, ashereindisclosed, is sub stantially I-shaped in cross section and has itsrear extremity bent or curved downwardly, as at 2, and to whichdepending portion is adapted to be secured, n the usual way, theconventional plow 3. I

At a predetermined point along the substantially horizontal portion ofthe beam 1 and to one side thereof is positioned the Application fiecinarcirii; 1914., Serial No. 924, 12."

block member l-having the recess .or,-.p'ocl et ,5, such block being:clamped to thebea n 1 through the medium of the clamping bolts 6passingabove and below the beam lwhreby it will be readily. perceivedthat such beam is inno wise weakenedas would be the case ifsuch boltswere directed through suitable openings in the beam, as is gen- Theclamping bolts .or mem- Z bers (Til/1S0 serve to holdinoperative-posttion against the opposite side of the beam 1, the depending member/4-formed on the forward extremity of the elongated member 8 whiclnservesas a brace for the raclrme1n her 9, the length of the member Sbeing suchas to permit the lower'angular portion 10 of the rackto be clamped tothebeam 1 at the bend thereof, such portion 10 being pro vided withsuitable openings through which conventional hoolcbolts areprojected inorder to create the requisite clamping action,

ina manner which isbelievedto be obvious.

Within the pocket or recess is suitably pivoted, as indicated at 11, thetorwardea ,trem ty of the subsoiler beam 12 which may be of any ordinaryor preferred construction and terminating in a proper position relativeto the plow To either side of the rack 9 the beam 12 is provided withthe upstanding straps l l, to the upper extremities 01. which aresuitably secured the bar 1-5, the rear" portion of such bar 15 beingextended, as indicated at 16, in order to afford a convenient handgrasp. Slidably mounted u )on the bar 15 is the spring actuated-pawl 1rnormally in engagement with the rack 9 but adapted to be disengagedtherefrom through the medium of the lever 18 pivotally connected withthe bar 15 andoverlyso a ing the projected or handle portion 16, such- 1lever being operatively connected with the pawl 17 through the medium ofthe link member 19.

When it is desired to regulate or adjust I the extent of penetration ofthe plow member 20 carried upon the lower extremity of the subsoilerbeam 12, 1t is only necessary that such beam be swung upon its pivotalconnection, with the block 1, through the medium of thebar 15, in amanner which is believed to be self-evident.

In order that the beam 12 will be efiect- ,ively maintained againstundue lateral movement, wefind it of advantage to have principles andspirit thereof and for this.

structed in accordance with our invention is r of anextremely simple andcomparatively inexpensive nature and is particularly well adaptedfor useby reason ofthe c0nvenlence and faclhty with which it may be assembledand by reason of the eiieetivenesswith which it performs its severalfunctions and it will also be obvious that our invention is susceptibleof some change and modification without material departure from thereason we do not wish to be understood as i limiting ourselves to theprecise arrange- 2O merit and formation of the several parts hereinshown in carrying out our invention in practice.

Having thus fully described our invention what we desire to claim andsecure by Let ters Patent, is: I 1 g In combination with a plow beam, ablock positioned to'one side of the beam and provided with an openingdisposed substantially parallel to the beam, an elongated memberpositioned above the beam and provided at one extremity with a dependingmember "overlying the beam at the side there of opposite to the block,clamping 1neans common to the block and the depending member for holdingthe same to the beam, a

. rack depending from the opposite extremity of the elongated' memberand overlying the ing within the opening of the block and pivotallyengaged therewith and of a length to project immune-y of the rack, a barpositioned above and carried by the subsoiler beam and provided with anextensionto afford a hand grasp, a latch mechanism oarried by thebar andenacting with the rack whereby the subsoiler beam may be main ta i nedin differing adjustments about its pivoted connection with the block,said latch including a member overlying the projected portion of thebar-whereby the latch may be operated by the hand in engagement with theprojected portion, the clamping means for the block and depending memberand the clamping means forthe rack constituting the only pointofengagement with the plow beam.

In testimonywhereof we hereunto aflix our signatures in the presence oftwo Witnesses.
